John Gill preaches on how David serves as a type of Christ, emphasizing that David's last words were prophetic and foreshadowed the coming Messiah. He highlights David's humble beginnings as the son of Jesse, his anointing by God, and his exaltation to kingship, paralleling these aspects with the life and ministry of Jesus Christ. Gill draws attention to the significance of David's psalms, which not only reflect his own experiences but also point to the sufferings and glory of Christ. He encourages believers to cherish the last words of both David and Jesus, as they hold profound meaning for faith and salvation. Ultimately, Gill calls for a deeper appreciation of the psalms as they reveal the character and work of Christ.
